Wanting to Deactivate Old SIM Card

[bedard98]

I recently had my phone stolen/lost and have since replaced it.

I downloaded an eSim card onto my new phone.

I am ready to resume my plan but want to make sure my old SIM card is deactivated.

How can I do this?

What can the cell phone vendor do with the old Sim? The sales guy gives me a new sim when I switched and when I asked if I can keep the old one he said yes, gives it to me but then says do you want a bag for it? Takes the sim card with him somewhere in the back and comes back with a baggie. Seems suspect in hindsight. Should I be concerned?

Hello! You can only have one SIM card attached to an account at a time. Once you replace that SIM the old one becomes de-activated and cannot be used again.

Since you’ve already purchased an eSIM that is attached to the account with the stolen SIM that old SIM is now de-activated and cannot be re-used. You can safely resume service if the eSIM was purchased for that same account as it would replace it as soon as the purchase was made.
